About

A troubleshooting reference for one specific problem: macOS on Apple Silicon breaks in ways generic advice doesn't cover, and most of what's written about it online was never actually run.

Why this exists

Search results for specific macOS symptoms are mostly recycled advice — the same five commands copied across a hundred sites, few of them verified against current hardware or a current macOS version. This site is the opposite bet: fewer articles, each one run command-by-command on real M-series Macs before it's published, with the exact chip, macOS version, and date shown so you can judge for yourself whether it still applies to your setup.

How it's verified

Every article is written and verified on the machines listed at Tested on. Every command in every article has actually been run — reads are shown with their real output, changes are shown with what they actually do and how to undo them.

How severity levels work

Every command on this site is labeled one of three ways, regardless of color: reads the system, changes settings, or irreversible. Destructive commands always carry a backup warning above the code, not after it — you should never copy a command you haven't finished reading.
